(1) Dear Alice, Are wet dreams in a sexually active 23 year old male unusual? ?Voice HAS cracked (2) Dear Alice, I only had about three to four "wet dreams" in my entire life and now I'm 20 years old. I wonder if it is normal, or it's because I masturbate often that I don't have these kinds of dreams. Is there a way of having one like that again? ? A Dreamer (3) Dear Alice, I have a normal sex ...

graduate school to study biology. At first, it was as if I was starting over, taking classes I had bypassed as an undergraduate, such as Introductory Organic Chemistry. But my motivation to master a new field made the experience enjoyable rather than frustrating. Moreover, I was captivated by the science. In my biology classes, I felt I was being offered gold nuggets of information that earlier...

Superhydrophobic surfaces let water droplets roll off with low friction and falling droplets rebound, leaving the surfaces completely dry. Such extremely water repellent surfaces are found in nature on lotus leaves, the legs of water striders and feather coatings of birds, and portray a beautiful example of ingenious biological design. They provide an exciting research avenue for physicists and...

Most studies on granular physics have focused on dry granular media, with no liquids between the grains. However, in geology and many real world applications (e.g., food processing, pharmaceuticals, ceramics, civil engineering, constructions, and many industrial applications), liquid is present between the grains. This produces inter-grain cohesion and drastically modifies the mechanical proper...

In the past a poor quality residue was frequently excused and accepted when incoming refuse had a high moisture content. This is no longer permissable. Means of coping with the wet refuse problem are summarized, based on reports from operators of IS municipal incinerators of various types, sizes and ages. The author's comments and conclusions are included.

The appearance of many natural materials is largely influenced by the environment in which they are situated. Capturing the effects of such environmental factors is essential for producing realistic synthetic images. In this work, we model the changes of appearance due to one such environmental factor, the presence of water or other liquids. Wet materials can look darker, brighter, or more spec...

Degradation of the extracellular basement membrane is implicated in atherosclerosis, restenosis after angioplasty, and intimal thickening of vein grafts. Upregulation of metalloproteinase (MMP)-2 and MMP-9 accompanies neointima formation in cholesterol-fed rabbits, in rat and pig models of angioplasty, and in organ cultures of human saphenous veins. MMPs are inhibited by binding to tissue inhib...

One of the improvements introduced by the Romans was the public bath-house. This article discusses the formation of Jewish prayers, which were composed during the early rabbinic period, following the dangers of the public baths. Sages from late antiquity published two prayers: Before entering to the bathhouse, the bather has to pray for his safety, and after leaving the bath-house he has to tha...

The main goal was to optimise the thermal conditions within a diving suit and improve the user’s comfort. The wet diving suit consisted of (i) an external neoprene layer with air bubbles as additional insulation, and (ii) internal textile clothing to improve the insulation effect. Both layers were connected as a composite because the friction coefficient is very high. The core temperature shoul...
